Jumpers; Clear Cmos Jumper: Jbat; System Configure Jumper: J2 - MSI E7320 Master-S User Manual

MS-9152 ATX Server Board
The motherboard provides the following jumpers for you to set the computer's
function. This section will explain how to change your motherboard's function through
the use of jumpers.

Clear CMOS Jumper: JBAT

There is a CMOS ROM onboard that has a power supply from external battery
to keep the data of system configuration. With the CMOS ROM, the system can
automatically boot OS every time it is turned on. If you want to clear the system
configuration, use the JBAT (Clear CMOS Jumper) to clear data.
MSI Reminds You...
You can clear CMOS by shorting 2-3 pin while the system is off. Then
return to 1-2 pin position. Avoid clearing the CMOS while the system
is on; it will damage the mainboard.

System Configure Jumper: J2

This jumper determines which mode the system will enter while powered on.
Under Normal Mode, the system will enter the assigned OS as usual. Under Config-
ure Mode, the system will directly enter BIOS setup utility. This enables you to modify
the BIOS configurations. Under Recovery Mode, you have to insert certain boot disk
into the floppy drive before powering on the system. After powered on, the system
will read the boot disk and enter DOS. This enables you to update the BIOS with a
Flash utility if necessary.
